1 PRODUCT DESCRIPTION
The A103 telephone is an intrinsically safe telephone designed for use in mining applications. It
has been design to be a direct replacement for the now obsolete A101 and A102 telephone.
The A103 telephone comprises of a carbon loaded glass filled polyester telephone encased in a
metallic surround which also contain the customer termination box referred to as the terminal
chamber throughout this document.
Note: The A103 telephone contains a BP004 which is an ATEX/IECEx certified rechargeable
battery only for use in GAI-Tronics telephones. This battery will be disconnected upon despatch
from the factory and will therefore need to be reconnected during the installation process.

indicating to the user that the call is about to be terminated. This is to ensure the A103 telephone
cannot be left in an off hook state indefinitely.
If the user wishes to continue with the existing call in progress, operate and release the ‘DA’ for a
further 90 seconds…

4 External Signalling OPTIONAL relay not fitted as standard
The A103 provides a galvanically isolated, normally open volt-free contact for an external signalling
device, which closes when a ring signal is received by the A103 telephone.
Connection to this contact is made via the terminal block located inside the termination chamber
labelled as B1 and B2.
The contacts are rated as follows:
5 Internal BP004 battery connection.
This battery will be disconnected upon despatch from the factory to prevent full discharge. It will
therefore need to be reconnected during the installation process before securing the termination
chamber cover.
To reconnect the battery, simply connect the 4 pin socket and plug inside the termination chamber together.
Note: The battery should be fully charged before use. If the battery needs to be recharged, see section
“Battery SAFE AREA tests” within this guide.
6 Programming and configuration changes
The telephone polyester enclosure must NOT be opened in the hazardous area !
Note: The polyester phone case must be opened to access the store button used during programmin g and
the jumper links for configuration changes.
To maintain the Ingress Protection level of IP 55, all attempts should be made to maintain cleanliness during
this process. Also ensure seals are located correct and free from damage.

the main PCB which is inside the polyester telephone enclosure rear casing.
To prepare for installation, undo the three retaining screws shown to remove the front casing from
the rear. The screws are not captive in the front casing; a 5mm Allen key is required.
Note: Do not remove the polyester telephone enclosure rear from the metallic surround as this is
not necessary.
Disconnect the ribbon cable at either the keypad PCB or the main PCB to prevent damage.
The A103 telephone is factory set to tone dialling (DTMF) as default (HD3 & HD4 set to the position as
shown below in Figure 3).

Casing is tightened down.
Check also that the environmental seal is in position.
Tighten the three securing screws firmly.
7 MAINTENANCE
The A103 telephone is based on highly reliable integrated circuits.
Under normal operation, the telephone is maintenance free with the exception of the BP004
rechargeable battery.
The BP004 is located within the termination chamber. Depending on usage and environmental
conditions a good battery will indicate a no load voltage of between 7.2 and 8 volts.
If the battery needs to be replaced carry out the following:
Isolate the line feeding the A103 so that no power is being applied before removing the
termination chamber cover.
Once the cover has been removed disconnect the battery plug.
Now remove the battery which is held on to the termination cover by two M4 screws, nuts
and washers. Note the nylon washers are located on the outside of the terminal cover to
ensure a good seal is maintained.
Fit the new battery in reverse order remembering to reconnect earth wire and battery plug.
The line can now be reconnected and the A103 telephone functionality checked.

7.1 BATTERY SAFE AREA TESTS:
The A103 telephone is designed to provide a charge current of 10mA to maintain a good charge
state on the BP004.
If however the BP004 has been allowed to discharge below 6.5 volts, it may be necessary to
remove the battery from the installation and recharge it at a higher current in a safe area.
To fully charge a battery:
Us the Austdac Battery charger part number BATT032, this charger can charge 4 batteries
at the same time.
Note: The battery should be replaced if after being charged the voltage remains below 7.2
volts.
7.2 PROCEDURES
A programme of regular external visual inspection and cleaning is recommended, with
particular attention being paid to -
Security of the installation.
Security and integrity of cable entries.
Security and integrity of the termination chamber cover (certification label) including the
